1.4 Sample professions Learning languages and finding out about other countries can be fun, as well as useful, and this unit is an introduction to the differences in culture and language about which we all need to be aware. There are 10 independent sections: any selection of them can be studied in any order. Some are about why knowledge of other languages and cultures can be important; others are about what it’s like to study a foreign language or to have a career using a foreign language. This unit is aimed at secoAuthor(s): The Open University
